Bidirectional flow channel pump station circulating water supply pipeline in hydraulic model test and implementation method
The invention provides a bidirectional flow channel pump station circulating water supply pipeline in a hydraulic model test and an implementation method. The bidirectional flow channel pump station circulating water supply pipeline comprises an inland river side water collecting tank, an outer river side water collecting tank, three sets of PVC pipes, a circulating pump, an electromagnetic flowmeter, a first gate valve, a second gate valve, a third gate valve and a fourth gate valve. The inland river side water collecting tank and the outer river side water collecting tank are mainly used for collecting water flow and simulating river channel water flow, so that incoming flow smoothly flows to the downstream; the PVC pipes form a whole circulating water supply pipeline system, and the water flow in the downstream side water collecting tank is extracted by the circulating pump and then is collected to the upstream water collecting tank; the electromagnetic flowmeter is mounted in the middle of a pipe network and used for measuring the water flow; and the first gate valve, the second gate valve, the third gate valve and the fourth gate valve achieve flood drainage and water diversion working conditions of the bidirectional flow channel pump station hydraulic model test by controlling different opening and closing combination modes. The bidirectional flow channel pump station circulating water supply pipeline is simple in structure and reliable in technology, the problem that time and labor are wasted due to the fact that the direction of the circulating pump needs to be changed during variable working condition testing of an existing bidirectional flow channel pump station hydraulic model test can be effectively solved, the bidirectional flow channel pump station hydraulic model test can be well completed, and the application prospects are wide.
水工模型试验中双向流道泵站循环供水管路及实现方法，包括内河侧汇水箱，外河侧汇水箱，三组PVC管，循环泵，电磁流量计以及一号闸阀、二号闸阀、三号闸阀、四号闸阀。所述内河侧与外河侧汇水箱主要作用是汇集水流，模拟河道水流，使来流顺畅的流向下游，所述PVC管组成整个循环供水管路系统，将下游侧汇水箱内水流经循环泵抽提后汇聚至上游汇水箱，所述电磁流量计安装在管网中部，用于测量水流流量，一、二、三、四号闸阀通过控制不同的开闭组合方式实现双向流道泵站水工模型试验的排涝以及引水工况。本发明结构简单，技术可靠，可有效解决现有双向流道泵站水工模型试验变工况试验时需调换循环泵方向而耗时费力的问题，能很好的完成双向流道泵站水工模型试验，应用前景广阔。
